.- provide an air cooling Patented Sept. 27, 1932 JOSEPH JAGZKO, OFYOUNGSTOWN, OHIO coonme AND EATING svsrm Application m February 4,1931-. Serial No. 513,250.

This invention relates to a cooling system and means for the same forsmall buildings,

homes, apartments and the like, and has for its main object to provide asystem and machinery of the type mentioned which will be simple inconstruction, comparatively inexpensive to manufacture, install andoperate and wherein only plain water is used as cooling medium. 7

Another. object ofthis invention is to provide means as characterizedhereinbefore in which the cooled air itself will aid in producin thenecessary power.

Still another object of this invention is to system and device of inwhich the air will be directl cooled without the intermediacy of anyother materials and the same air is used to cool and provide thepremises in question with fresh air. I

Still a further object of this invention is to provide a cooling system'of the character mentioned which in case of need may also be used forheating the premises in which it is the type characterize installed.

Still further objects of my invention will be apparent as thespecification of the same proceeds.

' In the drawing forming a part of this specification and attachedthereto:

Fig. 1 is a diagrammatic plan view of an air cooling system according tomy invention,

while Fig. 2 is a sectional elevation of the water cooler-used therein.

. Referring now to the drawing, by charactors of reference, the numeralsignates an electric motor or any other suitable outside source of powerwhich is adapted to drive an air compressor 11. Said air compressordraws the air through the intake pipe 12 either from the outside throughpipe line 13 or from the rooms to' be cooled through the pipe line 14 asindicated by the arrows 15 and 16, respectively, the proportion of theair from the two sources being adjustable through the use of the valves17 and 18.

- The air so drawn into the compressor 11 on a warm summer day has acomparatively high temperature (90 F.), and during compression' it willreach a San higher temperature, but will be fed through the houses acooling coil 22 circulating cold Water as available in the localit likeusual running water of a materially ower temperature than the air, andin which the air will be cooling water.

' The cooled compressed air now passes through a pipe line 23 into anexpansion air motor 24 wherein it expands, produces power, and will befurther cooled, and the air so cooled will be led to the premises to becooled by the pipe line 25as indicated by arrow 26.

t he warm summer air has midity, %90%, and the vapor in the air willalso be first compressed and overheated, but in the cooler the watercontent will be lowered according to the pressure of compression and thetemperature of the cooling water, so that ultimately the greater portionof the compressed and cooled vapor will be condensed. The remainin vaporwill expand in the air motor and will be further cooled thereby, butsince the air will be cooled in the expanding motor to a greater degreethan the vapor, the air will further cool said vapor and a good portionof said vapor will be again condensed.

My system has also incorporated therein a temperature regulator 27, inthe outgoing air line anda regulatin cooling water valve 28 in theintake line for the water. cooler which may be regulated in suchaomanner that the air and vapor mixture will leave the air motor at atemperature of about 44 F., thou h other degrees of cooling may beproduced therewith. I prefer a temperature of 44 F. for the cooled airand the vapor because at said temperature the air will contain such anamount of saturated Va or which upon the air warming to a prefera 1etemperature ot' 70 F. in the premises where in it will be used, it willhave the most favorable humidity, that is about 40%.

a very high hucooled according *to the temperature of the The expansionmotor 24 is-co'nnected a coupling and shafts 29 to the air compressor sothat the power produced thereby will aid the motor in driving saidcompressor. If the compressor is a rotating one then the expansion motor24 should be an air turbine, while if the compressor is operating with apiston, the air motorwill be of the same style and the two preferablywould work on the same piston rod.

The air cooler maysimply consist of a metal container 21 havm a coil 22passing through the same and fed ning water, the intake line beingindicated by the numeral and the outgoing line by character 31, thedirections of the movements of the air and the water being the 0ppositeto one another. The amount of the cooling water fed to the device may beregulated by a hand valve 32 and it alsowill be automatically regulatedthrough the thermostat 27, and valve 28 mentioned hereinbefore, andconnected by the. link mechanism 33, as will be understood.

A condensed water trap 34 may also be provided in the air cooler 20 ,andthe condensed water may be removed through a pipe line 36 by the use ofthe hand valve or through an automatic air trap, as is well known in theart. The air motor also has a condensed water remover 37 but no air trapis needed there. r

With my cooling installation I may also keep the usual kitchenrefrigerator in a proper condition as to temperature and for thispurpose I may branch off a cooling air line 38 to said refrigeratorwhich may pass through the same in appropriate cooling coils and thenreturn to the intake air line, as at 39.

I know that cooling devices based on similar principles as my hereininvention have been used, usually on large scales for theatres,oifice'buildings, etc., but the systems used there are too expensive andtoo complicated for small units, they usuallyemploy expensive andpossibly harmful outside materials and products and their operation alsois expensive.

My system may also be used in a reversed manner for heating the premisesin which it is installed, to raise the temperature in said premises in amoderate degree, as for instance from 32 F. to F. The operation of mydevice in such a caseis as follows: The compressor 11 will draw air fromthe outside only and the cooled air from the air motor 24 will bereturned to the outside. In the former air cooler 20 the air will againbe cooled, but the water in the coil 22' will be warmed up and its heatmay be used in appropriate radiators in the premises. It can be provedthat the amount of electricity used by the motor 10 in my installationwhen used as a heater will be only one-quarter or one-fifth of thatamount of current which by'th'e usual runwould be used if said premiseswere heated directly by electric current.

It is seen, that my air conditioning system is simplified to a singleone-motor driven apparatus and requires no additional refrigeratingfluids, as the air itself and its vapor content are subjected directlyto the process ofwrefrigeration and dehumidification.

It will be understood that changes and variations may be made in theparts and combinations of my invention and I hereby reserve all myrights to any and all such changes as are within the spirit of theinvention and the scope of the appended claim.

What I claim as new, is:

In a device for cooling rooms and the -like,ime ans to compress air,means to'cool the compressed air, means to expand such compressed andcooled air, said cooling means condensing the humidity of the air to apredetermined degree and being provided with means for removing theliquid so condensed, and means to convey said expanded air into thepremises to be cooled, said compressed air being cooled by watertravelling in a counter direction thereto, means to regulate theamount'of said cooling water, said means being operated by a thermostatin the cooled air line.
